BIRDS OF PENNSYLVANIA. 
Helminthophila celata (Say.). 
V 
Orange-crowned Warbler. 
Description. 
“Above grayish olive-green, rather brighter on the rump. Beneath entirely 
greenish yellowish-white, except a little whitish about the anus ; the sides tinged 
with grayish-olivaceous. A concealed patch of pale orange-rufous on the crown, 
hidden by grayish tips to the feathers. Eyelids and an obscure superciliary line 
yellowish-white, a dusky streak through the eye. Inner webs of tail feathers broadly 
edged wdtli white. 
Female with little or none of the orange on crown, and the white edgings to inner 
webs of tail feathers. 
“ Youyig lacking the orange entirely, and with two fulvous-whitish bands on the 
wings. Length 4.70; wung 2.25 ; tail 2.00.”* — Hist. N. Am. B. 
Habitat. — Eastern North America (rare, however, in the northeastern United 
States), breeding as far northward as the Yukon and Mackenzie river districts, and 
southward through the Rocky mountains, and wintering in the south Atlantic and 
Gulf States and Mexico. 
The Orange-crowned Warbler occurs in Pennsylvania as a very rare 
and irreg*ular straggler, during the spring and fall migrations. A fine 
male was shot by the late C. D. Wood, November 2, 1867, in Bucks 
county. Dr. Spencer Trotter records f the capture of a specimen in 
Philadelphia county. I have never met with this species. 
Helminthophila peregrina (Wils.). 
Tennessee Warbler. 
Description. 
Length 4.71 (average of four adult males); extent 7| (two males); wing 2.65 
(average four males); tail 2 or a little less. The female is a trifle smaller. Bill 
(dried specimens) maxilla blackish; mandible paler; legs blackish, feet brownish- 
yellow. Upper parts olive-green, brightest on rump; top and sides of head and 
neck, more or less ash-gray in some specimens ; below chiefly Avhite ; lores dusky ; 
a whitish ring around eye, and a line of same above it ; outer tail leather has an 
obscure white spot on edge of inner web near end. Specimens taken in the fall have 
most of ash-gray of head and neck replaced with olive-green, and the lower parts, 
except under tail-coverts and patches on abdominal region which are white, are 
greenish-yellow. 
Habitat. — Eastern North America, breeding from northern New York and 
northern New England north v^ard to Hudson’s Bay territory ; Central America in 
winter. 
The Tennessee Warbler, according to my observation, is found in 
eastern Pennsylvania as a very rare straggler during the spring migra- 
tion, but in the autumn (September) it is often common, frequenting 
apple orchards, woods and thickets. Although sometimes found quite 
plentifully as an autumnal sojourner in the eastern portions of the state, 
I do not regard it as a regular fall migrant east of our principal mount-
